Open Ended

What direction does heat flow in?

Multiple Choice

WHat happens if two objects that are touching have the same temperature?

• No heat transfer occurs between them.

• Heat will flow from one object to another.
• One object will become hotter than the other.
• The objects will explode due to equal temperature.

Multiple Select

The average kinetic energy of an object measures

• thermal energy

• temperature

• how hot or cold something is

• how fast your going

Multiple Select

Particles that have energy added to them generally are

• slower and have a lower temperature

• faster and have a higher temperature

• less dense

• more dense

Multiple Choice

What is thermal energy or heat energy?

• Thermal energy is the total kinetic energy of particles in a substance

• Thermal energy is how hot or cold an object is

• Thermal energy is the energy produced by electrical currents.
• Thermal energy is the energy stored in chemical bonds of molecules.
• Thermal energy is the average kinetic energy of particles in a substance

Open Ended

What is the difference between thermal energy and temperature?

Open Ended

In what situation would an object with a colder temperature have more heat energy than an object with a higher temperature?

Multiple Choice

If you have two identical objects, one is heated up and the other is cooled, which one will have a lower density because they have a larger volume?

• The heated object will have a lower density.
• The heated object will have a higher density.
• Both objects will have the same density.
• The cooled object will have a lower density.

What is specific heat?

• Specific heat is the amount of heat lost when a substance cools down.
• Specific heat is the heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
• Specific heat is the temperature at which a substance changes state.
• Specific heat is the total energy contained in a substance.
• Specific heat is how easy or hard it is top heat something up

Multiple Choice

If an object has a high specific heat what does that mean?

• It can absorb a lot of heat without a significant temperature change.
• It heats up quickly with minimal heat input.
• It cannot absorb any heat at all.
• It has a low thermal conductivity.

Multiple Choice

If an object has low specific heat what does that mean?

• It means the object can store a lot of heat energy.
• It means the object takes a long time to heat up and cool down

• It means the object remains at a constant temperature for a long time.
• It means the object heats up and cools down quickly.
